1. What is Potential Energy?

Potential energy is the energy stored in an object due to its position relative to other objects. Gravitational potential energy depends on an object's mass, height, and the gravitational acceleration.

2. How Does the Calculator Work?

The calculator uses the potential energy formula:

Where:

• \( PE \) — Potential energy (Joules)
• \( m \) — Mass of the object (kilograms)
• \( g \) — Gravitational acceleration (m/s²)
• \( h \) — Height above reference point (meters)

Explanation: The formula calculates how much energy is stored in an object based on its position in a gravitational field.

3. Importance of Potential Energy Calculation

Details: Calculating potential energy is crucial in physics, engineering, and various applications including hydroelectric power generation, mechanical systems, and understanding energy conservation principles.

4. Using the Calculator

Tips: Enter mass in kilograms, gravitational acceleration in m/s² (Earth's gravity is approximately 9.81 m/s²), and height in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard value for gravitational acceleration?
A: On Earth, the standard value is approximately 9.81 m/s², though it varies slightly depending on location and altitude.

Q2: Can this calculator be used for other planets?
A: Yes, simply adjust the gravitational acceleration value to match the planet you're calculating for.

Q3: What are the units of potential energy?
A: Potential energy is measured in Joules (J) in the International System of Units.

Q4: Does potential energy depend on the path taken?
A: No, gravitational potential energy depends only on the vertical displacement, not the path taken to achieve that height.

Q5: What is the reference point for height measurement?
A: The reference point is arbitrary but is typically chosen as the lowest point in the system being analyzed.
